It's volatile as all get out and I'm not going to call out any token by name but if you needed another nudge, you can absolutely cover the cost of power and the 9070 GRE (or even XT) itself before the warranty expires by mining (without holding/speculating), which has been my breakeven point for sidestepping any guilt I might feel from buying another flagship GPU.

But to reason in other direction, unless you absolutely need cards right now, you could throw that ~$1440 in a 6 month CD and let the 4.5% pay for the tax or shipping on a 10090 XT or whatever RDNA 5 flagship when those drop in about as much time. If it lands anywhere close to what the rumors are indicating it should be a fucking monster.

You'll be doing gamers a favour, coz the AI boom has be a slaughter for PC gaming. The price of RAM, storage, and graphics...
